Hi,
Has anyone seen this error before? It happens for me quite often, but not
always, on Dylan branch during initial parsing:
Parsing recipes...
ERROR: ExpansionError during parsing .../oe-core/meta/recipes-core/eglibc/eglibc_2.17.bb:
Failure expanding variable SELECTED_OPTIMIZATION[:=], expression was ${@get_optimization(d)}
which triggered exception NameError: name 'get_optimization' is not defined
ERROR: Command execution failed: Exited with 1
Looking at the code, I don't see anything suspicious:
# eglibc can't be built without optimization, if someone tries to compile an
# entire image as -O0, we override it with -O2 here and give a note about it.
def get_optimization(d):
selected_optimization = d.getVar("SELECTED_OPTIMIZATION", True)
if base_contains("SELECTED_OPTIMIZATION", "-O0", "x", "", d) == "x":
bb.note("eglibc can't be built with -O0, -O2 will be used instead.")
return selected_optimization.replace("-O0", "-O2")
return selected_optimization
SELECTED_OPTIMIZATION := "${@get_optimization(d)}"
It sounds like by the time SELECTED_OPTIMIZATION tries to make an assignment
with immediate var expansion, get_optimization() function is not yet defined.
This happens with high BB_NUM_THREADS and bitbake 1.18. Trying bitbake from
master on Dylan gives "AttributeError: 'NoneType' object has no attribute
'rfind'", but that's another story.
Anyone has any clues or suggestions? Thanks.
